Re: magnetising water?



Hi,

I suspect that at least the change in flow rate is simple
to understand. The iron filings "crystalize" or at least stick
together with the field on,
thus restricting the water's path. The change in conductivity, is probably
associated with the change in the concentration on ions from dissolved
minerals. Recall that distilled water is a very bad conductor.

Thanks

One of my students has come back from the summer with his IB Extended Essay
work for my perusal, and I find myself mystified: he claims to have
"magnetised" water.

He presented me with his apparatus: the outer iron armature of a motor, with
its coil in place, with the rotating part replaced by a plastic cylinder
with inlet and outlet tubes. Inside this goes a soft iron cylinder filling
most of the space, so that the water has to flow round it.

He presented me with his results: (i) he claims that the flow rate of the
water decreases markedly when a current flows through the coil (ii) he
measured density and refractive index and found no change after the water
had passed through the device (iii) he did controlled measurements of
conductivity and found a clearly detectable drop in this parameter after the
water had been "magnetised". The water gradually reverted to normal over a
few days.

Next he presented me with his reference. This is a "normal looking" science
book in terms of density of text, diagrams and formulas. I am unable to
evaluate it beyond this because it is in Russian. The title translates
roughly as "Magnetising of Water Systems" and the author is V. I. Klassen.
Publisher is Moscow "Chemistry" 1982. The student is unable to explain very
clearly what he understands from this book, but says the effect has
something to do with the bond angle in the water molecule changing. I am
mystified and skeptical.

I've asked him to reproduce his measurements in our lab: in the meantime,
can anyone enlighten me as to what this effect might be? Is there a
reference in English, or at least a name for the phenomenon that I might
follow up?
